Patent abstract
An improved fluid flow gauging device includes a light enhanced acrylic block flow tube to optimize visualization of pressure readings. An LED or other light source is fitted to the top of the flow tube and illuminates a float or bobbin from above to provide more accurate readings, especially in low light conditions such as modern operating rooms. In addition, the light enhanced flow tube provides a mechanical backup in the case of failure of newer electronic systems and visually matches the graphical flow display, simultaneously providing a double-check of the electronic system.
